4.3.14.55.1 Content

This code system http://hl7.org/fhir/discriminator-type defines the following codes:

CodeDisplayDefinition
value ValueThe slices have different values in the nominated element.
exists ExistsThe slices are differentiated by the presence or absence of the nominated element.
pattern PatternThe slices have different values in the nominated element, as determined by testing them against the applicable ElementDefinition.pattern[x].
type TypeThe slices are differentiated by type of the nominated element.
profile ProfileThe slices are differentiated by conformance of the nominated element to a specified profile. Note that if the path specifies .resolve() then the profile is the target profile on the reference. In this case, validation by the possible profiles is required to differentiate the slices.

CodeThe code (used as the code in the resource instance). If the code is in italics, this indicates that the code is not selectable ('Abstract')
DisplayThe display (used in the display element of a Coding). If there is no display, implementers should not simply display the code, but map the concept into their application
